there is no sense in having different animals, always full room of the same sort makes the biggest profit. Just breed new ones and sell the old if the new is born, infinite money and quick progress...
for creator: you should add something like decreasing marginal revenue...so if you get the first animal of a kind you get for example +3% popularity, if you get another one you get +3*(1/x²)%, 3rd one gets you +3*(1/x³)% and so on...so there is less sense in going for one species only
if you just grind a level with many easy to get presents you can buy all upgrades before even playing all levels...makes it to easy to get the achievements... 4/5
bug found: one of the green things fell down, while kitty was attacking and is now stuck between falling and walking, so i cant pass it, without touching and cant shoot it, because it is above me.
